2896 loaded with the linker search paths (-L arguments) and the libraries
2897 to be linked with the current source (-l arguments). Changes
2898 currently will affect only the pic16 port.
2899 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2900 include path the port specific paths and port specific libraries,
2901 * gplink command now contains the $3 argument,
2902 * src/pic16/device.h,
2903 * src/pic16/device.c,: structure PIC_device is made public and

2919 Documenting changes from previous commits.
2920 * configure.in (version 1.56),
2921 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2922 when generating output files to configure the pic16 library,
2923 but now I've commented it out, since gputils aren't installed in the
2924 SF compile farm, so library won't compile
2926 * device/lib/Makefile.in (version 1.56): initially I've added in
2927 target 'all' the prerequestive 'model-pic16' so it compiled the
2928 pic16 library, but now I've commented it out for the same reasons
2930 * added targets 'model-pic16' and 'objects-pic16' to compile the
2932 * added target 'port-specific-objects-pic16' to handle the
2933 generated libraries and copy them into the build/ directory
2934 * added target 'clean-intermediate-pic16' to clean intermediate
2935 files into pic16 directory
2936 * in target 'installdirs' added line to create directory pic16 in

3202 * src/SDCCsymt.c (newEnumType),
3204 * support/Util/SDCCerr.c,
3205 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
3207 * support/regression/tests/enum.c: added test for enum values that
3208 require at least 2 bytes of storage.
3210 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3212 * src/common.h: added ifndef/define/endif macros
3213 around the header file.
3214 Bug reported from Jesus Calvino-Fraga
3216 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3218 * sdcc.spec: updated
3219 * device/include/Makefile.in: don't install CVS directories
3220 * device/lib/Makefile.in: added removal of CVS directories after install
3221 * doc/Makefile: fixed install, added local_icons
3222 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3223 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3224 * src/ds390/gen.c (genRightShift): fixed bug #870788
3225 * src/SDCCast.c (decorateType): fixed bug #870781
3227 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3229 PIC16 port related changes:
3230 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3231 added variable stackPos,
3233 * gen.c: genCall, assignResultValue: added support for
3234 pushing/retrieving function parameters to/from stack,
3235 genFunction,genEndFunction: setup stack frame for the
3237 genAddrOf: will be changed according to bug 863624
3239 * added files genutils.c and genutils.h which contain gen*
3240 debugged and optimised functions extracted from gen.c
3242 * glue.c: added variable 'externs' which holds extern symbols,
3243 pic16emitRegularMap: is modified to properly handle relocatable
3244 symbols under the new scheme,
3245 pic16createInterruptVect: is modified
3246 pic16printPublics: is modified to emit 'global' assembler directives,
3247 added pic16_printExterns to print extern symbols,
3248 pic16glue: initializes stack/frame pointer in the beginning of
3249 the assembly output. Temporary hack, will be corrected later,
3250 because gplink yet does not support stack and SDCC does not
3251 yet support a type of crt0.o object to create the final binary.
3253 * Removed many lines that contain 8051 legacy code.
3254 * The code is finally placed under a 'code' directive.
3255 * Added port specific options.
3257 * _process_pragma: simplified since now we do not need *special*
3258 include file to define SFR registers. But a separate header
3259 will be needed. This will be developed later.
3260 * _pic16_parseOptions: added, parses port specific options:
3261 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3262 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3263 --preplace-udata-with=
3265 * _pic16_setDefaultOptions: modified to initialize section names,
3266 but hack is temporarly out of order since it needs improvement.
3267 * _pic16_genAssemblerPreamble: configuration words are emitted by
3268 their address instead of their name. This part is incomplete and
3269 supports only the 18Fxx2 devices. Other devices will emit an error
3270 during assembly since they do not contain the same set of config
3272 * _pic16_genIVT: is modified,
3274 * pcode.c: added definitions for some hardware registers that are needed
3276 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3277 All PCI entries are updated. Now LFSR is supported.
3278 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3279 * added pic16_newpCodeOpLit2 to support instructions with
3280 two literal arguments
3281 * pic16_pCode2str: corrected code that emits assembler instructions
3282 with two literal operands and those that have an access bit modifier
3283 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3284 this fixes a bug which caused some labels to be lost, when an
3285 assembler directive was added, i.e. banksel,
3286 * pic16_FixRegisterBanking: improved logic that causes the insertion
3288 * InlineFunction: functions that are called once, are not any more
3289 inlined. This can be a port option in the future,
3291 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3293 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3294 hold the corresponding uninitialized symbols,
3295 * pic16_allocProcessorRegister: registers have explicit marked the
3297 * pic16_allocInternalRegister: registers are explicit marked as
3299 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3300 processing list, so bit registers were lost,
3303 * ralloc.h: added field 'accessBank' and original symbol operand
3304 in register definition,
3305 * removed the field isMapped from register definition,
3307 ** Several functions have been removed from various sources:
3308 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3309 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3310 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3311 pic16_assignRelocatableRegisters
3313 ** others have been introduced:
3314 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3315 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3317 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3319 * support/scripts/inc2h.pl: changed definition of BIT_AT
3320 to emit 'sbit at' instead of 'bit at'. This was a request.
3322 PIC16 port related preliminary changes:
3323 * gen.c: prefixed function popRegFromString with
3324 pic16_ and all references to it corrected
3325 * pcode.c: all pic16_pc_* hardware registers prefixed
3326 with underscore (_),
3327 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3328 * ralloc.c: newReg(): when register is REG_SFR then
3329 set address to rIdx,
3330 pic16_allocProcessorRegister(): marks register wasUsed=0
3331 pic16_writeUsedRegs(): added a call to assign processor
3332 registers via pic16_assignFixedRegisters
3334 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3336 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3337 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3338 variables in unused register banks. Also the SSEG is placed
3339 wherever there is enough space for it, and IDATA can be anywhere
3340 in internal RAM. For now compile using -Wl-Y[stack_size].
3341 The mem file is different for this option as well, since it
3342 makes no sense of talking about DSEG lenght.
3344 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3346 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3347 in certain cases, e.g. when ROM assignment, patch provided
3348 from Albert den Haan.
3350 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3589 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3591 * src/SDCCast.c (decorateType): disabled a transformation I added in
3592 revision 1.188 (access to fields of a structure at an absolute address);
3593 it breaks with bitfields, extern declarations, and gcse analysis.
3594 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3595 could be assigned through a pointer, so don't complain.
3596 * src/SDCCast.c (astErrors),
3598 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4236 support for standard C idiom of memory mapped variables; for
4237 example, *((xdata int*)0x1234) = 1 is now internally equivalent
4238 to xdata int at 0x1234 tempvar = 1.
4239 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
4240 provided by Akiya ISHIDA

4256 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4258 Fixed bug #621531 (const & volatile confusion in the type chain).
4259 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
4260 refer to the const or volatile state of the pointer itself.

4351 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4352 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4353 fetching of the pointer
4354 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4355 copied from genNearPointerSet()
4356 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4357 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4358 If they pop r0/r1 they must be called in the opposite order than aopOp().
4359 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4360 (resp. --stack-auto), prepared for --xstack

4371 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4373 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4374 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4375 type for bits was changed. It resulted in bit variables becoming
4376 global, which is not permitted in PIC 14 assembly output.
4378 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4380 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4393 A few small changes that speed up the peephole optimizer.
4397 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4399 Try to make the peephole optimizer smarter by maintaining
4400 an association between the assembly source code and the
4401 iCodes that originated them. Put this information to use
4402 with a new peephole rule condition "notVolatile" so that
4403 the rules can be aggressive yet still safe.
4408 * src/mcs51/peeph.def
4410 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4414 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4415 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4416 if the left or right operand symbols have the accuse flag set.
4418 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4420 Changed the type of the result of the ! (NOT) operator to char;
4421 previously it returned the same type as the source. This allows
4422 us to eliminate all the genFloatNot functions (all of its target
4423 implementations were very buggy) since !float can use the same
4426 * src/SDCCicode.c (ast2iCode): ! returns char

4435 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4436 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4437 during interrupts. Ensure WSAVE is located at a shared bank address.
4438 2. Fixed page selection in some places
4439 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4440 the registers name strings.
4441 4. Fixed "signed / unsigned compare" compiler warnings.
4442 5. The PIC port manages its own allocation of the general purpose
4443 registers, but makes no attempt to reuse them. As a result when
4444 compiling it soon runs out of general purpose registers. Some
4445 additional code was added to the files pcode.c and device.c to walk
4446 through the function call tree and rename the registers so that they
4456 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4457 genPlus() & genMinus() when the result is the same as left or right

4463 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4465 Made bitfield a distinct type from bit so that bitfields
4466 convert as per ANSI C and bits retain their traditional
4467 boolean style behaviour. Implemented bitfield support in
4475 * src/ds390/gen.c: bit v bitfield split
4476 * src/z80/gen.c: New support for bitfields
4477 * support/regression/tests/bitfields.c: reenabled z80,
4480 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4482 Rules 246.x, 247.x relate to bitfields, the others speed up
4483 access to xdata mapped I/O devices.
4485 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4487 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4489 Cleaned up genPackBits and genUnpackBits and added two helper
4490 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4491 for literal assignments in genPackBits (thanks to Frieder for
4497 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4499 Fixed bug #748310 (pointer to function type mishandled when the
4500 function name is omitted). Also fixed a SIGSEGV when a function
4501 attribute (reentrant, etc) is used on a non-function or on a
4502 function but misplaced before the parameter list.
4504 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4506 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4507 * support/Util/SDCCerr.h,
4508 * support/Util/SDCCerr.c: Added func attr misuse error msg

4529 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4531 Made the constant following the "interrupt" keyword optional. If
4532 omitted, the function will not automatically be given an entry
4533 in the interrupt vector table (similar to #pragma NOIV, but
4534 less syntacticly kludgy). The interrupt number is also now
4535 range checked. Also fixed a bug in the high order bit example

4548 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
4549 * src/SDCCicode.c (operandOperation): rewritten some ops
4550 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4551 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4553 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4554 be re-activated by defining REDUCE_LITERALS)
4555 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4556 unsigned, but are signed by default
4557 * src/SDCCval.c (constVal): rearranged
4558 * src/SDCCval.c (valMod): preliminary fix
4559 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4602 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4603 * src/SDCCval.c (valDiv, valMod): fixed signdness
4604 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4605 signedness of modulo, left and right shift

5065 added if/endif conditional macros to remove options help
5066 messages from optionsTable when a port is not configured, added
5067 support for the PIc16 port in the ports table, when executing
5068 the compiler with no port specified on command line, a default
5069 port is selected with the new macro DEFAULT_PORT which is
5070 defined in port.h, in setDefaultOptions() linkOptions is removed
5071 from initialization assignment, since now it is a set,
5072 parseCmdLine uses setParseWithComma for linkOptions, in
5073 linkEdit() linkOptions are accessed with new function indexSet()
5074 which returns the i'th item of a set variable. See SDCCset.c, in
5075 linkEdit() when calling buildCmdLine(), added linkOptions as
5076 last argument. Now users can pass arguments to gplink via the
5077 -Wl option, main() uses pic16glue() to glue up pic16 programs

5091 gpasm complaining and test the linkage with gplink, _linkCmd and
5092 _asmCmd changed to be more gplink and gpasm friendly
5093 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5094 produced an error when parsed, peep rule 12 is added to utilize
5095 movff, but it is commented out since the pCode does not support
5096 yet a command with 2 address arguments
5098 2003-05-18 <johan AT balder>

5127 2003-05-11 Borut Razem <borut.razem AT siol.net>
5129 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

6129 2003-01-06 <karl AT turbobit.com>
6130 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
6133 2003-01-06 <johan AT balder>
6135 * src/SDCCicode.c: fixed array add
6137 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6138 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6139 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6141 2003-01-04 <johan AT balder>
6143 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6145 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6146 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6148 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6149 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
6150 * support/regression/tests/bug-524697.c: fit mem usage into 8032
6152 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6153 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
6155 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6156 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6158 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6159 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6161 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6163 * in \sdcc\as\mcs51\ changed these files in order to create an
6164 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6165 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6166 following files to include the previous two files: aslink.dsp,
6167 Makefile.aslink, Makefile.bcc, and Makefile.in.
6169 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6170 .adb instead of .cdb
6172 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6174 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6175 value from option --iram-size.
6177 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6179 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6182 2002-09-18 <wiml AT hhhh.org>
6184 * SDCClrange.h: exposed setFromRange() and setToRange()
6185 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6186 packRegsForAccUse() (bug 542397)
6187 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6188 multiple times and emitting the fetch operations more than once
6189 added aopGetUsesAcc() function to allow binary operators to
6190 fetch their operands in the correct order; made genMinus() emit
6191 compact code for X = LITERAL - Y
6193 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6194 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6195 sprintf() in line 1267.
6197 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6198 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6201 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6202 Changes to aslink (All the changes are marked with 'JCF'):
6204 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6207 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6208 area BSEG. Also moves, if possible, the DATA area down into the internal
6209 ram so more space is available.
6211 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6214 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6215 not bytes. Function summary() which creates a memory usage summary
6216 file with extension .mem. Reports of overlaping stack and small stack
6217 size. If the space for the stack is less than 16 bytes aslink trows a
6220 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6221 the 8051. Option 'y' for memory summary output file.
6223 Changes to sdcc (All the changes are marked with 'JCF'):
6225 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6227 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6228 overlaying area for it (uses RegBankUsed[4]).
6230 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6231 bank zero as used by default. By default aslink locates the stack
6232 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6233 the creation of the .mem file. Delegates the allocation of data area
6234 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6235 the begining of the stack area to aslink.
6237 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6238 glue() in SDCCglue.c creates an area for it.
6240 2002-09-03 Borut Razem <borut.razem AT siol.net>
6241 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6242 sdcc/src/pic/glue.c:
6243 introduced atexit() handler for teporay files removal in case of
6244 errors, assertions, ...
6246 2002-08-29 Borut Razem <borut.razem AT siol.net>
6247 * sdcc/support/cpp2/auto-host_vc_in.h:
6248 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6249 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6250 Maybe there is a similar problem with BORLANDC? It should be checked!
6252 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6253 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6254 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6255 was not executed, and the compiler (cl) launched a warning:
6256 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6258 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6259 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6261 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6262 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6264 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6265 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6266 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6267 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6268 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6269 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6270 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6271 - added Release configuration in VS projects
6272 - review of compiler an linker options
6273 - VC .exe files are generated in bin_vc directory, not to interfere
6274 with binaries generated from other projects (cygwin, mingw, bcc ...)
6276 * sdcc/src/yacc.dsp: added
6278 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6279 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6280 and insert the version number definitions from .version
6282 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6284 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6285 added - genarate auto-host.h using auto-host_vc_in.h as template
6288 removed from CVS, generated automatically
6290 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6291 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6293 2002-08-11 Borut Razem <borut.razem AT siol.net>
6294 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6296 2002-08-10 Borut Razem <borut.razem AT siol.net>
6297 * src/SDCCmain.c (main):
6298 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6299 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6300 The consequence was that some temporary files were not removed.
6303 unification of code in functions tempfilename() and tempfile():
6304 function tempnam() is defined in Visual Studio 6.0 and .NET
6306 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6308 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6309 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6310 - removed compiler command line option /WX: Treats all warnings as errors
6311 - update a list of source files, included into the project
6313 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6314 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6315 changed project type to Generic Project so that can be correcly converted to VS.NET project
6317 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6319 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6321 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6323 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6324 added return 0 statements after assert() to make compiler happy
6326 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6327 added newline in the def file to keep MSC compiler satisfied
6329 * sdcc/src/z80/gen.c:
6330 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6331 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6332 - solved MSC error in function aopDump()
6334 * sdcc_vc.h: define PREFIX as "\\sdcc"
6336 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6337 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6339 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6340 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6341 - Rewrote the register banking algorithm.
6342 - Added pCode live-range analysis to registers (for now, only non-used and
6343 singly-used registers optimized away)
6345 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6347 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

6372 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
6374 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6376 2002-03-28 Johan Knol <johan AT balder>
6378 * src/SDCCval.c: fixed bug #532436
6380 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6382 Added "char *Processor" field to the port structure.
6385 Added -p option. Allows port dependent processor to be specified.
6388 Initialized the new field char *Processor field to NULL in all ports
6391 Compiler generated registers for interrupt context saving
6392 were not getting allocated.
6394 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6397 Fixed left shift. Will promote the left side of a left shift
6398 if a) left shifting more than size of operand or b) when assigned
6399 to something size > size of left side
6401 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6403 tons of changes. Register allocation has been
6404 rewritten. Added customization for the various PICs. Flow
6405 analysis is restructured. ...
6411 Added. device.c is a PIC port hack to accomodate variations
6414 2002-03-13 Michael Hope <michaelh AT vroom>
6416 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6418 2002-03-04 johanknol <johanknol AT manik>
6420 * /src/SDCCval.c: fixed
6422 const unsigned char arr[][2] = { { 0, 1 } };
6423 t18.c:1: error: Initializer element is not constant
6425 2002-03-04 bela <bela AT manik>
6427 * /device/include/mcs51reg.h:
6428 ds89c420 register definition update
6430 2002-03-03 <johan AT FRIJA>

6509 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6511 * sdcc/src/SDCCloop.c:
6512 Previous fix was not good. basic blocks that have "break" or "return" are
6513 not really partof a loop , but live ranges used in these blocks should
6514 be live thru the entire loop, so set partOfLoop but don't add them to
6517 2002-02-21 <johan AT FRIJA>
6519 * src/SDCCcse.c: fixed bug #514308
6521 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6524 Fixed BUG #519583. If a conditional block ended in a return/break
6525 statement inside a loop, it was not being considered part of the loop.
6527 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6529 2002-02-10 Karl Bongers <karl AT turbobit.com>
6532 Fixed up SDCDB debugger somewhat. Updated debugger/README
6533 with lots of comments and notes.
6535 * device/examples/test2.c:
6536 Fix bug, "red" variable not being initialized(compiler complained).
6538 * device/examples/Makefile, examples/test3.c:
6539 Add Makefile in device/examples folder, compiles test3.c
6540 for use as a multiple module SDCDB test case.
6542 * sim/ucsim/cmd.src/cmdset.cc:
6543 Took out debug printfs in ucsim "next" command.
6546 Karl and Johan start ucsim XA support. Most dissassembly working,
6547 about 75% emulation done(plenty of work remaining).
6549 * sim/ucsim/z80.src:
6550 Add Z80 support to ucsim, add test-ucz80 regression test,
6551 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
6552 Notice z80 compiler fails on examples/test3.c/crc code.

6566 3) added __builtin_swapw swap bytes of a short
6568 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
6569 1) handle multiple send & receives from register bank1
6570 2) ralloc can now allocate DPTR1 to some liveRanges
6572 * src/SDCCsymt.c, src/SDCCsymt.h:
6573 changes to handle multiple sends & receives
6576 added some pointer arithmetic optimization
6579 added some pointer arithmetic optimizations but not stable yet so not
6580 called from anywhere (will get this working shortly)
6582 * src/SDCCopt.c: fixed for multiple sends & receives
6585 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
6586 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
6587 set preprocessor defines (depending on options)
6589 * src/SDCCicode.c, src/SDCCicode.h:
6590 changes made to handle multiple sends & receives
6593 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
